Carbonates

Practical Applications of Carbonates. Permanent hard water contains HCO 3-.By adding Na 2 CO 3 (washing soda), the water is softened and hard water precipitates calcium and magnesium. Ammonium sulfide group filtrate, when treated with CO 3 2-, yields precipitate from the fourth group (Mg, Ca, Sr, Ba). Aqueous carbonate anion is the key reagent, earning the …
